[Touch-packages] [Bug 1584575] Re: /lib/systemd/system/lightdm.service file has no [Install] clause
Thanks @Craig - helped someone in #ubuntu on 17.10, and I experimented on 18.04 and found it is still a problem there too. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to lightdm in Ubuntu. https://bugs.launchpad.net/bugs/1584575 Title: /lib/systemd/system/lightdm.service file has no [Install] clause Status in lightdm package in Ubuntu: Confirmed Bug description: This concerns lightdm 1.18.1-0ubuntu1 in Xenial.

[Touch-packages] [Bug 1584575] Re: /lib/systemd/system/lightdm.service file has no [Install] clause
I too needed to re-enable graphical login after having disabled it. I can confirm adding: [Install] Alias=display-manager.service to my /lib/systemd/system/lightdm.service file. Allowed me to re-enable lightdm to start on boot (by running "sudo systemctl enable lightdm"), previous to this I would end up booting to a black screen with a flashing cursor in the top left. Ctrl+Alt+F1 (for VT1) etc... would lead me to the login prompts, Ctrl+Alt+F7 leads me back to the screen with the flashing cursor (VT7). So for me Ubuntu was expecting a graphical interface to be running and had me on VT7 at boot. Logging in from one of the other terminals showed lightdm to be stopped ("systemctl status lightdm"). Prior to the fix above I would have to manually start lightdm by logging in and running "sudo systemctl start lightdm" I hope the above helps anyone googling the issue as it took me a couple of hours to track down why it wasn't starting when I thought it was re- enabled. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to lightdm in Ubuntu. https://bugs.launchpad.net/bugs/1584575 Title: /lib/systemd/system/lightdm.service file has no [Install] clause Status in lightdm package in Ubuntu: Confirmed Bug description: This concerns lightdm 1.18.1-0ubuntu1 in Xenial.

[Touch-packages] [Bug 1584575] Re: /lib/systemd/system/lightdm.service file has no [Install] clause
Maybe make display-manager.service into an actual service file (rather than a symlink), and have that start whatever /etc/X11/default-display- manager points to? What I want is to be able to disable and then re-enable the display manager starting on boot using similar administrative commands, like a "systemctl disable/enable" pair. Even better if the argument to the commands is the same in both cases. (Possibly even better yet if default-display-manager could be set to some "null" option, so you can disable/re-enable the display manager without ever touching systemd...) -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to lightdm in Ubuntu. https://bugs.launchpad.net/bugs/1584575 Title: /lib/systemd/system/lightdm.service file has no [Install] clause Status in lightdm package in Ubuntu: New Bug description: This concerns lightdm 1.18.1-0ubuntu1 in Xenial.

[Touch-packages] [Bug 1584575] Re: /lib/systemd/system/lightdm.service file has no [Install] clause
This whole systemd thing is new to me, and I can't say I'm terribly enamored of it, so I'm not the best person to ask. But by way of example, I'll point out what a couple other .service files do: /lib/systemd/system/rsyslog.service: [Install] WantedBy=multi-user.target Alias=syslog.service /lib/systemd/system/ssh.service: [Install] WantedBy=multi-user.target Alias=sshd.service I'm pretty sure the LightDM file should have "Alias=display- manager.service", but can't say if "WantedBy" should be "multi- user.target" or "graphical.target" or something else. ** Changed in: lightdm (Ubuntu) Status: Incomplete => New -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to lightdm in Ubuntu. https://bugs.launchpad.net/bugs/1584575 Title: /lib/systemd/system/lightdm.service file has no [Install] clause Status in lightdm package in Ubuntu: New Bug description: This concerns lightdm 1.18.1-0ubuntu1 in Xenial.
